v This iiiivention relates to a feed -mechanism,:andit is particularlyan object of the invention to provid des gned. and jadapted for use nconnection with a dusting mechanism for vide a device of this kindembodying an agiitating Wheelworking within a hopper and whichwheel isof such construction toeliminate the liability, ofthe dust within thehopper,

to mai ntain ing' of the" hopper. '1

A further objectof the invention is to provide a mechanism of this kindincluding a 'plateadj ustable with respect'to the discharge opening ofthe 'liopper'forregulating and proaches stopping up."

controlling the discharge from said hopper andwherein is employed anagitatingwheel which, during this" rotation, "closely apthedischargeopening of the hopper to thereby prevent said opening from Astill further object of the invention is to a provide an'apparatus ofthis kind wherein the supply hopper a there is provided below thedischarge from container to collect dust 'whichwould otherwise probablybe lost upon slowingup or stoppin'gof the dusting apparatus. v Theinvention consists in the details of construction and'in the combinationand ar-' rangement' oftheseveral parts'of my im- 7 whereby certainimportant advantages are attained an'd the device rendered "simpleryless expensive and otherwise more convenlent and advantageous I i ropenings for use, as w ll beliereinafter more fully set forth.
